Re: Temperature ratings
One company I worked for had a rack in a south facing 3rd floor room, with large windows. The CEO got air con in his office, but he declared the IT had survived this long without AC, it didn't need it.
The "trick" was, the first person in in the monring opened the windows wide to allow the air to circulate... :-S
I installed a thermometer in the room and in the rack. Average summer temperature in the room was 38°C. The middle of the rack was approaching over 60°C!
Interestingly, we only had one server throw a hissy fit, an 8 year old HP server. The rest (only 6 years old) all ran stably throughout the summer! We did however borrow an air compressor in the June and cleaned the dust out of every machine in the rack, 6 years worth of dust isn't good for the lungs!
